VALVE FOR POWDER DISTRIBUTORS.

Application filed October 1, 1920. Serial No. 413,959.

I0 all whom it may concern: 7

Be it known that I, CHARLES J. W'orInR,

citizen oftheiUnited States, residing at Springfield, in the county of Robertson and State of Tennessee, have invented certain ,new and useful Improvements in Valves for Powder Distributors, of which the following .'is a specification.

This'invention relates to improvements in A valves for dispensing devices or distributors especially adapted for use in spraying insecticides andfungicides and the like on to plants, shrubs, trees,'-etc.

The invention forming the subject matter ofthis application aimsrto provide apowder distributor of-the class described having a A-rfurther object ofthe invention is to is simple to operate, durable :in use and cheap to manufacture. i

Other objects and advantages of the iiivention will beapparent during the course I of the following description.

In the accompanying drawings, forming a part of this'application and in which like numerals are employed to designate like parts throughout the same;

Figure 1 is a side elevation of the improved powder distributor in use.

Figure 2 is a vertical detail sectional view through the reservoir and one of the valves,

Figure 3 is a vertical detail sectional view taken on line 3-3 of Figure 2.

Figure 4: is a perspective View of a valve embodied in the invention,

In order that the valve and its use may be fully and readily understood, I have shown a powder distributor and will describe some of its essential features of con struotion and operation.

In the drawings, the numeral 15 designates a cylindrical blower which may have a plurality of fan-containing compartments. Air is taken into the compartments through openings 29 formed in the central portions of the side walls of the blower. The end portions of the fan shaft are fitted through openings in the intermediate portions of straps 30 which extend across the openings 29 and are secured to the sides of the blower by means of rivets 34 or other suitable fastening devices.

With reference to Fig. 2, it will be observed that a shaft 44; is extended through the lower portion of a reservoir 47, and suitable means for rotating said shaft and the fan shaft is, of course, provided.

It might be stated that the reservoir 4? is adapted to contain a powder which it is desired to spray over rows of plants, shrubs, bushes, or trees, for destroying either fungus or insects. The powder is introduced into the reservoir 47 through an opening which is normally closed by means of cap. The reservo r, which is arranged in advance of the blower, is provided in its under side with an opening or openings 56-which permit the discharge o the powder 111tO;(llS

charge members 58 of tubular formation.

The rear portions of the discharge tubes 58 are enlarged as indicated at. 59 and com- 'municate with the lower portions of the fan compartments. Therefore, upon the rotation of the fans within the blower, ablast .of air is created which is directed through the enlarged portions 59 of the discharge tubes 58 so that a quantity of powder is drawn through the openings 56 into the dis charge tubes.

With reference to Fig. 2 it will be observed that brushes 60 are keyed or otherwise secured to the shaft 44 within the reservoir 47 and are rotated during the operation of the device so as to agitate the powder whereby the powder is caused to pass through the discharge openings 56 uniformly. The brushes 60 are arranged di rectly above the openings 56 and therefore eiiioiently direct the powder through the openings in addition to thoroughly agitating the same. The discharge members are provided with openings 64 which are alined with the openings 56 so as to allow the powder to readily enter the discharge members. However, each discharge member is provided with a sleeve valve 66 having one side provided with an elongated opening 68 which is adapted to be alined with the openings 64- and 56. When the sleeve valve is partially rotated by means of the adjusting member or lug 70 the opening 68 may be brought out of registration with the opening 64: so as to cut off communication between the reservoir and the discharge member. \Vhen it is desired to merely re duce the flow of powder from the reservoir, the opening 68 may be brought only partly out of registration with the opening 6% in the member 58. The handle 70 of each sleeve valve 66 is arranged within an arcuate slot 72 in the lower portion of the discharge member 58. In the use of the device, the sleeve valve is securely held in position by means of the handle 70 and as the ends of the sleeve valveare entirely open, the powder may readily flow through the same. Then open, the sleeve valve does not in any way interfere with the passage of the powder or the air through the discharge member 58. The sleeve valve is, of course, held inadjusted position by frictional contact with the inner side walls of the member 58.

As illustrated the forward portion of each discharge member 58 is provided with a bent coupling 75 to which a discharge spout 77 is connected. The coupling 75 of each spout 77 is adjustable so that the inclination or angle or the spout T7 with relation to the evicemay be adjusted according to the will of the operator. The forward por tion of each spout 77 is flared and flattened, as indicated at 80, so as to more eificiently spread the powder over the adjacent plants and the like. Since the forward portion of each dis harge spout 77 is provided with a flared head or nozzle 80, the powder is spread over a maximum area. 7 e

The device may be attached to ones person by means of a belt 80 having an in termediate portionprovided with an attaching plate to be detachably connected to the rear portion of theblower.

The device may be further secured to ones person by means of a belt or strap 88 adapted to be passed about the shoulders and secured to loops 89 by means of hool-zs 90. One section 92 of the strap 88 is provided with a. buckle -93 loynieans of which the effective length of the strap may be side adapted for registration with the open ing in said casing, and a radial handle connected to said tubular member and extending through said casing. i

2. A device of the classdescribed comprising a straight tubular casing open at' both ends and having an entrance opening in one side, an open-ended sleeve valve arranged longitudinally within said tubular casing and having an opening in one side adapted for registration with said entrance opening, said casing being provided with a circumferentially extending slot, at a point remote from the entrance opening, and a radial handle depending from said sleeve valve and extending through said slot.

In testimony whereof I afiix my signatu re. s
